android - dalvikvm 堆 : Out of memory on a 73547536-byte allocation

Question

我已经释放了每个对象，回收了 onDestroy() 方法中的所有位图:

     private void unbindDrawables(View view) {
    if (view.getBackground() != null) {
    view.getBackground().setCallback(null);
    }
    if (view instanceof ViewGroup) {
        for (int i = 0; i < ((ViewGroup) view).getChildCount(); i++) {
        unbindDrawables(((ViewGroup) view).getChildAt(i));
        }
    ((ViewGroup) view).removeAllViews();
    }
}
@Override
protected void onDestroy()
{
    super.onDestroy();
    unbindDrawables(findViewById(R.id.RootView));
            bitmap.recycle();
            bitmap=null;
    System.gc();

}

我在每个类的 onDestroy() 方法中都完成了这个编码。但我的 logcat 仍然向我显示如下错误:

标题说明了一切——您正试图一次为一张图像分配 73 兆字节 的堆。仅此一项就超过了大多数现代设备上可用的堆大小——64 兆字节。您需要找到一种方法来使用明显更小的图像。
